摘要
结构力学作为土木工程专业的一门核心基础课程,知识点较多,逻辑关系复杂;而超静定结构有多种计算方法,更是其中的难点。笔者根据多年教学探索与实践,提出对于同一例题,采用力法、位移法、力矩分配法、无剪力分配法与矩阵位移法进行求解,并对计算方法、过程进行了总结与比较,重点在于让学生掌握各种方法之间的联系与差异,有利于土木工程专业学生更为系统地掌握超静定结构多种解法的要点,从而更深入地掌握各种求解的方法与技巧。
Lots of knowledge points and complicated is one of the core basic courses in civil engineering. logical relationships are in structural mechanics, which The problem seems to be more difficult for the statically indeterminate structure because there are several calculation methods for one case. A teaching model is proposed in this study based on teaching exploration, in which a problem is calculated by Force Method, Displacement Method, Moment Distribution Method, No Shear Distribution Method and Matrix Displacement Method and practice. The calculation methods and processes are summarized and compared. The connections and differences between various methods are investigated. The concept, and the calculation details of multi-solutions of statically indeterminate structures is demonstrated more clearly in the proposed model, which is more convenient for the learning.
